Customer Ratings & Reviews

This is the absolute best motor oil on earth! Soon after I started using this oil for my 2002 Lexus ES300, I noticed all kinds of improvements with the performance of my engine. Granted Toyota makes excellent vehicles, this oil still brings it to the next level. I now have 380,000kms on my car and it runs like a clock! I can't even hear my engine when I sit at red lights!! Completely dependable motor oil by the inventors of synthetic motor oil. Using anything else just doesn't make sense to me. Please note that I do not work for, or have any affiliation with Amsoil, and I'm not getting paid for the statement I just made. It's truly based on my personal experience with this motor oil.

Great product!!

Started using Amsoil for my motorcycles. Now my Jeep and all power equipment: Honda generators, husqvarna snow thrower, boat and in and on. Every piece of equipment runs great. Amsoil is my only choice, they earned it.

I have been running this oil in my truck since new .. I haven’t had any problems . Keeps my 8 year old Chevy running like it did when it left the factory if not better

I chose AMSOIL 0W-20 Signature Series for the demonstrated protection it offers which is backed up by data.

I highly recommend Amsoil overall, the product is of the highest quality and the value it provides is unmatched.

Just put some in my 1994 Ford Club Van. It’s very good quality. I also like the ability to order other things in addition to the oil. With the press of a button I can order other things for my van, for the year and put them in. I like this convenience.

I've been a mechanic most of my 65 years and I've seen a lot of garbage that is supposed to be "good" for cars, but AMSOIL is the real deal. I use it in all 4 of my vehicles and as many of my friends that I can convince that this stuff is worth the money.

Hello, I've been using amsoil Signature Series Synthetic for over a year now. This oil is designed to last for 25,000 miles and combined with the absolute efficiency oil filter it is one of the best oils on the market. I could not be more pleased. I have full confidence that this oil will last in any condition that I can put my vehicle through. I will continue to use amsoil because the orders are always correct shipping is always expedited and doing it myself was the best decision for my vehicle.

Use the best, ride hard

This is the best oil I’ve ever used in my vehicle period. Sounds better, drives smoother, and it provides more confidence knowing I can push my car to the limits safely.

I put it in my Toyota Tacoma, it made a big difference went i was towing my travel trailer. I will not go back.

The motor oil I recently purchased from AmsOil was 0W-30. It does a great job keeping the vehicle engine alive and running nice and smooth. I have had absolutely no issues once I started using AmsOil motor oil in my vehicle. Strongly and definitely recommend using their motor oil and their products in general!!!
